Abstract

Evaluation of existing diagnostic procedures for the recommendation of trace element fertilizers.

To compare the accuracy and reliability of a range of tissue and soil tests being variously promoted for use to farmers for the diagnosis and prognosis of zinc and copper deficiencies in wheat crops on Western Australian farms.

Trial 66N14

Long term copper residual trial at the Newdegate Research Station.

To determine the residual value of previously applied copper.

Location: Newdegate Research Station.

Trial 86N27

Residual value of zinc with high analysis nitrogen and phosphorus fertilizer.

To determine the decline in effectiveness of zinc on this soil types using DAP

Location: Newdegate Research Station.

Trial 86LG34

Residual value of copper, zinc and sulphur with high analysis nitrogen and phosphorus fertilizer under continuous cropping situation.

To determine the decline in effectiveness of copper, zinc and sulphur on this soil types using DAP.

Location: South Newdegate.

Trial 67E8, 67E9

Effects of rates of nitrogen on copper concentrations, dry matter production and grain yield of lupins grown on a residual copper trial.
